The dull color may also be accompanied by a powdery or chalky texture, which you can easily rub off the material. This occurs when the aluminum is exposed to air, allowing oxygen to interact with its surface and form a layer of aluminum oxide. Oxidized aluminum looks dull and often develops a chalky white coating. Other ways to prevent corrosion include using an appropriate protective coating and regularly cleaning and maintaining aluminum surfaces.Īdditionally, since corrosion needs to access the metal surface in order to occur, keeping the surface clean is key to minimize corrosion. Exposure to these elements, combined with water and heat, will cause aluminum to corrode more quickly.Īnodizing, a process that helps strengthen and protect aluminum by creating a thin ceramic layer on its surface, can help slow corrosion. Such elements include sodium chloride (salt), sulfur dioxide, ammonia, chlorine and oxygen. Unfortunately, aluminum can corrode quickly if it is exposed to elements that cause chemical reactions. Therefore, the length of time it takes for aluminum to corrode in water depends significantly on the composition of the solution, and the conditions under which it is exposed. In more aggressive solutions, such as those containing high levels of sulfuric acid, aluminum can corrode in a relatively short period of time, often within a few days or weeks. In general, however, aluminum exposed to fresh water is not particularly susceptible to corrosion, and typically takes several years to corrode significantly. The rate at which water corrodes aluminum can vary greatly depending on a variety of factors, including the type and concentration of dissolved solids and other chemicals in the water, the temperature and pH of the water, and the amount of oxygen present. How long does it take water to corrode aluminum? To help reduce corrosion, it is best to treat aluminum with a protective coating, such as paint, anodizing, or sealant.Īdditionally, regular maintenance, such as cleaning and inspection, can help prevent and detect corrosion. However, humidity and other environmental conditions can accelerate corrosion. This oxide layer prevents further corrosion and acts as a protective coating. Aluminum is a reactive metal, meaning it can easily give up electrons to oxygen in water, which form an oxide layer on the surface. It is an oxidation-reduction reaction, known as galvanic corrosion. Yes, aluminum can corrode when exposed to water. Taking preventive measures and treating the metal promptly can help minimize the damage caused by water and prolong the life of the aluminum. In some cases, it can create a white powdery substance known as “white rust” or “aluminum oxide” that can build up, turn yellow, and eventually become black. When water does come into contact with aluminum, the metal quickly begins to corrode, leading to weakened structural integrity, a decrease in strength, and a decrease in aesthetic appeal. The corrosion process, commonly known as oxidation, is accelerated in the presence of salt or other contaminants.Īs a result, aluminum should never be allowed to come into contact with water for long periods of time. Aluminum is a reactive metal and is prone to corrosion when exposed to water and oxygen. Is aluminum water resistant?
